Dan Evans became the third British man to reach the third round of the US Open singles with a confident win over Australia's James Duckworth.
British number two Evans, seeded 20th, won 6-3 6-2 4-6 6-4 against his 83rd-ranked opponent in New York.
Former world number one Andy Murray and rising star Jack Draper won their second-round matches on Wednesday.
Cameron Norrie, the nation's leading player, looks to join them in the last 32 when he faces Portugal's Joao Sousa.
Seventh seed Norrie, who reached the Wimbledon semi-finals in July, followed Evans out on court 12 as he aimed to match a career-best run at Flushing Meadows.
